WORK-POSITIONING: MECHANISM Application filed June 15,

Essex, respectively, and State of Massachusetts, have invented certainimprovements in lVorlcPositioning lvlechanisms, o Which the followingdescription, in connection With the accompanying drawings, is aspecification, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates to mechanism for positioning Work such, forexample, as shoe stock for the performance of operations thereon, andthe embodiment of the invention hereinafter specifically described willbe set forth With particular reference to its application to theinsertion of fastening-s in toplifts of heels.

In the manufacture of shoes of certain kinds, it is customary to affix atoplift to the heel of a shoe by metallic fastenings inserted adjacentto each of the breastcorners of the toplift and at the back of thetoplift respectively. The head ends of the fastenings are visible 011the tread surface of the heel of the finished shoe, for which reason itis desirable to the end that the heel may present a symmetricalappearance that the fastenings be spaced equidistam'vly from the contouredge of the toplift, and that the fastenings inserted adjacent to thebreast corners of the toplift be disposed equidistantly from the breastedge or" the toplift and be spaced from the breast edge of the topliftby a distance bearing a definite relation to the distance by which theyare spaced from the contour edge of the toplift, the distance by Whichthe fastenings are spaced from the breast edge of the top lift beingsubstantially equal to the distance by which they are spaced from thecontour edge of the toplift.

In order that fastenings may be inserted symmetrically in heels ofdifferent sizes and to attain uniformity of appearance of shoes havingheels of varying sizes, it is further desirable that the spacing of thefastenings from the. ed 'es of the heel be proportioned. to the sizes ofthe heels so the fastenings will be spaced farther from the breast edgeand contour edge of a large heel than from the correspondingSpecification of Letters Patent.

edges of a anall heel. Accordingly, an important feature of theinvention resides in the provision of means for positioning the breastcorners of a heel successively at substantially equal distances from thepoint of operation on the heel and adjustable for dilferent sizes ofheels so that the point of operation on a large heel may be disposedfarther from the breast edge of the heel than from the correspondingedge of a smaller heel. Preferably, and, in the illustratedconstruction, the positioning means comprises a plurality of gagemembers so connected that an adjustment of one of said members effects acorresponding adjustment of the other.

in accordance with a still further feature of the invention, one of aplurality of gage members is mounted for movement by the Work relativelyto the other gage member to facilitate the operation on a heel of amachine employing an and feed by which the Work is moved from theposition in which it is first presented to the machine prior to thecompletion of the operation of the machine thereon. Preferably and asshown the movable gage member is normally urged yieldingly toward theother member and is so constructed as to cause its gaging surface tomove substantially in the direction of the movement of the work.

In the illustrated embodiment of the invention, the positioning meansfor the toplift comprises members formed to present shoulderedsurfacesfor engagementrespectively with the breast corners of a topliftand With other gaging surfaces arranged for engagement with the contouredge of the toplift, the contour edge gaging surface of each of saidmembers being arranged to engage the contour edge of a heel when abreast corner of the heel is presented against the shouldered gagingsurface of the other gage member.

Although the invention will be hereinafter described as applied to amachine for inserting fastenings at three points, for example, forattaching a toplift to a heel, it is recognized that the invention isnot restricted in its application to such specific use. and it isfurther recognized that the members and the means for mounting andadjusting them may be modified Without departing from the principles ofthe in- 1 vention. It is, therefore, intended that the scope of theinvention shall be limited only as required by the language of theappended claims. 7 r

' Fig. 7 is a View showing the relative arrangement of the toplift andthe gage members for the insertion of a fastening adjacent to the backof the toplift.

The work positioning mechanism is herein illustrated as applied to afastening inserting machine of the type employed for inserting headlessfastenings formed from wire, such fastenings being generally denominatedslugs and a machine for in.- serting such fastenings being disclosed inthe patent to Casgrain No. 786,190, granted March 28, 1905. Asillustrated, the frame 6 of the work positioning mechanism is pivoted tothe head 2 of the fastening inserting machine at 4, and slidably mountedin a boss formed on the head 2 of the machine is a spring pressedplunger 8 cotiperating with the inclined surface 10 formed on one of thebosses 12 of the frame 6. The plunger 8 operates normally to retain thework positioning mechanism in its operative horizontal position butyields to permit the frame 6 and the parts carried thereby to be turneddownwardly on the pivot 1.

Mounted on the frame 6 are gage members 14; and 16 formed to presentshouldered gag ng surfaces 18 and 20 for engagement with the breastcorners of a toplift and preferably curved gaging surfaces 21 and 22 forengagement with the contour edge of the toplift. The fastenings areimpelled into the toplift by a driver 23, openings being made in thetoplift through the instrumentality of an awl 24 to receive thefastenings inserted by the driver. The gaging surfaces 18 and 20 are soarranged relatively to the awl-asto position the toplift in such mannerthat the and when projected downwardly penetrates the toplift at thepoint where the fastening should be inserted.

It is desirable, in order to make the dif ferent pieces of work uniformand symmetrical in appearance, that the fastenings be inserted at agreater distance from both the contour edge and the breast edge of thetoplift in operating on a relativelylarge toplift than when operating ona smaller toplift. Means are provided for adjusting the gaging surfaces18 and 20 to adapt the work positioning mechanism for use in operatingon toplifts of varying sizes, and we have so constructed the adjustingmeansfor the gage members 14: and 16 that an adjustment of one of saidgage members to adapt it for use in operating on a toplift of a certainsize will effect a corresponding ad justmeut of the other gage member toadapt it for use in oaerating on a toplift oflike size. To this end, thegage member 14 is fulcrumed at 26 on the carrier or plate ,28

slidably mounted in the frame 6, and the gage member 16 is connected tothe gage member 1 1 by a pin and slot connection comprising the pin 80and the slot 31 whereby movement of the gage member .14 is transmittedto the gage member 16. The gage member 1 1 is'adjusted about the fulcrum26 by means of a handle 32 and is maintained in any position ofadjustment to which it may be moved by a bolt or the like 3-1 whichpasses through a slot in the. plate 28. The pin 30 and slot 31 form aconnection between the gage members lt and 16 whereby adjustment of thegage member 14 effects an equivalent adjustment of the gage member 16and also permit movement of the gage member 16 independently of the gagemember 14. for a purpose to be hereinafter set forth.

Fig. 5 shows in full lines the position in which a heel B comprising atoplift A is presented to the machine. As shown,. the breast corner ofthe heel B isv engaged with the shouldered gaging "surface 20 of thegage member 16. From an inspection of Fig. 5, it will be apparent thatif the gaging surfaces 18 and 20 are moved toward each other, thefastening will be inserted in closer proximity to the breast edge oftheheel than before, whereas, if the gage members 1 1- and 16 are adjustedaway from each other, the fastening will be inserted at a in the frame 6and toothed or corrugated .opposite the handle 42. A spring ie at theend of the shaft 05 is interposed between nuts 46 and the me 6 and ertsfriction whereby the ier :28 is maintained in any position of adjustmentto which it may be moved. From the fore going it will be plain that, ifheel of greater size than the preceding heel is to be operated upon, thehandle will be manipulated to move the members 1e; and 16 away from eachother which will cause the fastening to be in. greater distance from thebreast ed 3 heel. The handle 4:2 will also be manipulated to move gagemembers 14; and 16 rearwardly away from the plane of operation of thefastening inserting mechanism which will increase the distance by whichthe fastening will be spaced from the contour edge of the heel.

In the operation of the fastening inserting machine, the awlv is movedlaterally subsequently to its projection into the work to bring theopening thus made in the work into alinement with the driver Each of theshouldered gaging surfaces 18 and 20 has-a portion arranged transverselyof the direction of movement of the work and intersecting with thecontour edge gaging surface 21 or 2:2, the angle thus formed engagingthe breast edge of the heel when the heel is presented to the fasteninginserting machine indicated in Figs. 5 or 6. In order to permit movementof the work by the aw]. we have so mounted the gage member 16, which iscarried by that side of the carrier 28 toward which the work is moved bythe a-wl. as to permit said member 16 to be moved. by the work independently of the gage member 14;, To this end, the gage member 16 isfulcrumed at 4L8 on the link 50 which is in turn fulcrumed at 52 to thegage slide or carrier 2-8. The link 50 and the gage member 16 carriedthereby are normally urged toi'vard the gage member 14L by a spring 5%which yields to permit movement of the member 16 when the work is fed bythe awl. Movement of the gage member 16 toward the member 14: is limitedby stop 55 Fig. 2.

The awl moves in a substantially straight line and in order that thework may be effectively guided and supported while it is being fed bythe awl, we so control the movement of the gage member 16 as to causethe gaging surface 20 thereof to be moved substantially in a straightline and parallel to the path of movement of the aw]. Thus theinclination of slot 31 in arm 56 of the gage member 16 is such. as toprevent substantial inward or outward movement of the gaging surface 20as link5,0 is swung about its pivot 52. against the end of the slot inthe arm 56 of the member 16 limits the movement of the gage member 16under the impulse of the spring and thus determines the normal positionsof the gaging surfaces 20 and 22.

A horn 58 may be provided for supporting the heel against force exertedthereon by the fastening inserting mechanism.

The operation of the/device will. heapparent from an inspection of Figs.5, 6 and lhe heel m. be presented to the fastening inserting mechanismin the position shown in :T l lines in Fig. 5, following which the awlpenetrates the heel at the point indicated by the upper small circledefined by a full line and moves it and the gage member 16 to thepositions shown in broken lines in said figure, the point of fasteninginsertion being indicated by the lower circle defined by a broken line.Analogously, the full lines in Fig. 6 indi- 7 of the drawings.

cate the position in which the heel is pre-. sented to the fasteninginserting mechanism for the insertion of a fastening adjacent to theother breast corner of the heel, and the broken lines indicate thepositions to which the parts are moved by the aw], the lower circleindicating the point of fastening insertion. In Fig. 7 is indicated infull lines the position in which the heel is first pre- Thepin 30 actingsented to the fastening inserting mechanism 7 for the insertion of afastening adjacent to the back 0 the heel, the parts being moved fromfull line position to broken line position by the aw]. followingpenetration of the work by the awl. In each case, the gage member 16 ismoved. backwardly in opposition to the action of the spring 54: topermit movement of the work from the position indicated in full lines tothe position indicated in broken lines. It will be understood that theorder in which the several fastenings are inserted may be varied at thewill or convenience of the operator.
